Specification of Letters Patent.

Patented July 15, 1919.

Application filed September 13, 1916. Serial No. 119,873.

To all whom it may concern Be it known that we,WILL1AM O. BUN- NELL andQUINCY A. GATES, citizen of the United States, and residents of Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have inventedcertain new and useful Improvements in Street Indicators, of which thefollowing is a specification.

The present invention relates to card, picture and sign exhibiting andhas particular reference to new and useful improvements in changeableexhibitors for streets, stations and the like when used in connectionwith street cars or railway trains.

The primary object of our invention is to provide a novel and simplestreet and station indicator for street cars, railway trains and thelike which may be operated by the conductor 0r motorman, or may beoperated automatically.

Another object of our invention is to provide a changeable exhibitor ofthe class described having alarm means associated therewith fordirecting attention of the passengers and others to the indicationsgiven by the device.

A further object of our invention is to provide a changeable exhibitorof the class described which is strong and durable, effective inoperation and cheap to manufacture and maintain.

Other objects and advantages to be derived from the use of our improvedchangeable exhibitor will appear from the following detailed descriptionand the claim, taken with the accompanying drawings, in which- Figure 1is a longitudinal sectional view of a street car showing a pair of ourimproved indicators installed thereon;

Fig. 2 is an enlarged longitudinal vertical sectional view of anindicator embodying the improvements of our invention; and

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 2looking in the direction of the arrow.

Referring more particularly to the draw- 4 ing, wherein similarcharacters of reference designate like and corresponding partsthroughout the various views, 1 designates the housing of our improvedstreet indicator the same having a sight opening 2 in one wall thereof.

The exhibiting mechanism of our improved indicator includes a rack bar 3having a plurality of openings 4 formlng teeth.

A wheel 5 is provided mounted upon a shaft 6 and rotatable therewith,said wheel having a plurality of radially extending pins 7 forengagement with the openings 4. The rack bar is movable in guides 8, thefree end of the rack bar being connected to a strap 9 which may extendthroughout the length of a railway car or train.

Apinion 9 is mounted on the shaft 6, said pinion being connected with agear 10, said gear being carried by roller 11 ournaled in the side wallsof the housing 1. A web 12 having thereon the names of streets,advertising matter, or any other indications to be exhibited is woundabout the roller 11, the web being trained over a roller 13 and thenwound upon a roller 14. A crank 15 is provided for engagement with theroller 14 to rewind the same after a run.

To maintain the rack bar 3 in normal position we provide a pair ofretractile springs 16 connected to one wall of the housing and to a pin17 extending downwardly from said rack bar.

An alarm mechanism is provided for directing attention of passengers andthe like to the indicator, said mechanism including a pair of bells 18between which is pivotally mounted a hammer 19. The lower free end ofthe hammer is adapted to be engaged by oppositely arranged enlargements20 formed on the rack bar, a pair of retractile coil springs 21serving'to maintain the hammer in the normal posltion as shown in Fig.2.

When installing the device a pair of the same is employed, the samebeing designated. A and B in Fig. 1 and being placed adjacent the end ofa railway car C. Supports 22 may be provided throughout the length ofthe car carrying the strap 9. A roller 23 is disposed beneath the rackbar 3 adjacent a point at which the same engages with the wheel 5 so asto prevent buckling of the rack bar.

A spring pressed pawl 24 is carried by the wheel 5 to engage the pinion9 when an impulse is given to the rack bar, the pawl permitting returnof the rack bar to normal position after a movement of the web. Thecrank 15 may be employed to rewind the web after each run. Both of theindicators are independently operable from either platform of the car soas to each indicate the station or street.

From the above description taken in connection with the accompanyingdrawing, it

is thought that a clear and comprehensive understanding of theconstruction, operation and advantages of our invention may be had, andwhile We have shown and described the device as embodying a specificstructure, We desire that it be understood that such changes may be madein said structure as do not depart from the spirit and scope of theinvention as claimed.

Having thus fully described our invention, What We claim as new anddesire to secure by Letters Patent, is:

In combination with a changeable exhibiter having horizontally alinedWays in its lower portion, movable exhibiting means, an actuating barpassing through the cas- Gopies of this patent may be obtained for fivecents each, by addressing the ing and slidable in said Ways connected tothe exh bitlng means for operatlng the same, sa1d bar having a lugformed With a pocket on its upper side, bells arranged in the caslng, ahammer pivoted in the casing havlng one end thereof engaged wlth thepocket in sa1d lug and spring means connected to sa1d hammer and saidactuating bar for normally maintalnmg the same 1n neutral positionwhereby to permit actuation of the hammer upon sliding movement of theactuating bar in either direction.

In testimony whereof, We affix our signatures hereto.
